Business Process Mapping (BPM) is a tool used to document and analyze the steps involved in a business process. It can be used to identify inefficiencies, document processes for training purposes, and provide a framework for process improvement initiatives. BPM is typically broken down into five levels of detail, each providing a different level of detail and insight into the process.

Level 1 provides a high-level overview of the process, showing the main steps and the relationships between them. It is useful for quickly understanding the overall process, and can be used to identify potential areas for improvement.

Level 2 provides a more detailed view of the process, showing the individual tasks and activities involved. It is useful for understanding the flow of the process and the roles and responsibilities of each participant.

Level 3 focuses on the activities and tasks, providing a detailed view of the process. It is useful for identifying potential bottlenecks and inefficiencies.

Level 4 provides a detailed view of the individual tasks and activities, showing the inputs, outputs, and resources required. It is useful for understanding the cost and time associated with each task.

Level 5 provides a detailed view of the process, showing the specific tools, techniques, and technologies used. It is useful for understanding the specific requirements for each task, and for developing process improvement initiatives.

Overall, Business Process Mapping provides a powerful tool for understanding and improving business processes. By breaking down the process into five levels of detail, it is possible to gain a comprehensive view of the process and identify potential areas for improvement.
